Methodology: How We Ranked the Best Solar Companies in Smithtown

EcoWatch's solar experts analyzed each solar company in Smithtown based on criteria such as its reputation in the industry, customer reviews, services, warranty coverage and financing. Using this solar methodology, we used the data we collected to rate and rank each company and narrow down our picks for the best solar companies in Smithtown


Below are some the criteria we examined specifically for New York solar companies

  • Brand reputation and certifications (20%): We take each company's Better Business Bureau (BBB) score into consideration, as well as how long the installer has been in business (at least 5 years is required, 10 preferred) and what type of solar certifications it holds.
  • Customer reviews (20%): Trust is a top priority at EcoWatch, so we take customer experience under close consideration. We scour different review sites and customer testimonials when ranking our top solar companies, checking sites such as Trustpilot and Google Reviews. We also consider any potential complaints or lawsuits filed against these companies and award or remove points accordingly.
  • Warranty (20%): A company earns a perfect score in this category if it offers 25-year warranties that cover performance, product and workmanship. The industry standard that we measure companies against is 25-year product and performance warranties, along with a 10-year workmanship warranty. We also look closely into the track record of the post-installation support each company provides in terms of honoring its contracts
  • Solar services (10%): All of the companies we review install solar panels, but we award companies higher points if they offer additional services for customers, like battery installation, energy-efficiency audits, and EV chargers.
  • Pricing and financing (10%): It's hard to get exact quotes for solar projects, but we use marketplace research to determine how each company prices its equipment and installation services. Additionally, companies that offer more help for panel financing — like in-house loans, leases, or PPAs — score higher than those that don't.
  • Availability (10%): The bigger the service area, the higher the company will score.
  • Transparency and accessibility (5%): Solar installers that offer free consultations and easy contact methods score higher in this category.
  • Environmental, social and corporate governance factors (5%): A company earns a perfect score in this category if it offers public data disclosure, addresses end-of-life (EOL) products or processes, and demonstrates a commitment to uplifting the communities that it serves.

The Cost and Benefits of Solar in Smithtown

For a lot of homeowners, the decision to invest in a solar energy system boils down to the cost.Some significant things that influence how much it will cost and how much you could save include:

  • Average daily sunlight: Since Smithtown gets a decent amount of average daily sunlight, your solar panels can generally produce enough energy to power your whole home, which affects how much your electricity bills will be.
  • System size and type: Some models are more pricy than others, so the one you choose can raise or lower your initial investment. Plus, the more solar panels you need to buy, the more it'll cost.
  • Incentives: The federal solar investment tax credit currently allows you to reduce your taxes by 0 of the project cost. Your state and city may also have various incentives that you can take advantage of. Plus, you can save about $22,000 over 20 years on your utility bills, not including incentives.
  • The cost of electricity in your area: If your local power rates are high, there's a good chance you'll end up with a higher return on your investment in solar panels. In Smithtown, you can save an average of $1,525 a month on your electricity bills.

There are many wonderful benefits of solar despite the upfront cost of installation. It can help the planet and your bank account. Additionally, it can increase the value of your home, resulting in even more benefits if you decide to sell your home later.

Environmental Impact of Switching to Solar in Smithtown

There are a few big reasons why homeowners are interested in solar energy: to put more money in their bank account and to help the planet.You may be curious – how much does making the switch help the planet anyway? According to the EPA, electricity generation is the second largest source of greenhouse gas emissions and about 62% of our electricity is generated by burning fossil fuels. Switching to a clean energy source like solar power can help lower that statistic in a city like Smithtown that produces a large amount of carbon dioxide emissions each year.Because solar panels don’t release carbon dioxide emissions into the atmosphere when creating electricity, they’re a good alternative to traditional energy sources. In fact, you could look forward to lowering your carbon dioxide emissions by about 100 pounds each year. If you care about the environment, you’ll most likely recognize that there are many benefits of adopting solar energy other than just saving money on electricity. You can also help preserve the environment, which some would argue is priceless.

What are the best and worst things about solar power?

A few of the biggest pros are that it lowers your power bills, it’s eco-friendly, and it can give you a good return on your investment (ROI). The most notable cons are that solar panels don’t work as well when there’s limited direct sunlight, they cost a lot upfront and solar panels aren’t always aesthetically pleasing.

Is it worth putting solar panels on my roof?

Solar panels can be a beneficial investment for most homeowners, but honestly, they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight or your power bills are already reasonably low, solar panels might not be for you.

What is the efficiency of solar panels?

Solar panel efficiency is the amount of energy from the sun that is converted into electricity. Most panels today have an efficiency rating of about 15 to 25%. If your panels are more efficient, you'll need fewer of them to meet your home's energy needs.
